我在我的一个应用程序上遇到错误,每个月发生几次,但本周发生了两次.当这种情况发生时,第一个用户加载应用程序并开始工作时,它总是第一件事(Web应用程序,3-4个内部用户)错误源于这个非常简单的方法,一旦失败,它将无法工作,直到我重启应用程序池.现在,我也以其他方式查询AD,但这是用户在早上开始工作时调用的第一个AD相关方法.

public DomainUser GetDomainUser(string userLoginName)
    {
        using (PrincipalContext context = new PrincipalContext(ContextType.Domain,this.DomainName))
        {
            using (UserPrincipal user = UserPrincipal.FindByIdentity(context,userLoginName))
            {
                // If user is null,the result is not a UserPrinciple
                if (user != null)
                {
                    string firstName = user.Givenname;
                    string middleName = user.MiddleName;
                    string lastName = user.Surname;
                    int empId = Convert.ToInt32(user.EmployeeId);
                    string emailAddr = user.EmailAddress;
                    string userName = user.SamAccountName;
                    DateTime? accountExp = user.AccountExpirationDate;

                    return new DomainUser
                    {
                        FirstName = firstName,MiddleName = middleName,LastName = lastName,EmployeeId = empId,Email = emailAddr,UserName = userName,AccountExpiration = accountExp
                    };
                }

                return null;
            }
        }
    }

因此,this问题密切相关,但我的权限设置正确,代码在99％的时间内正常工作,并将在应用程序池重新启动后继续运行.

堆栈跟踪看起来像这样：

问题是什么？内存泄漏？常见的模式是,当第一个用户开始使用应用程序时,这首先发生在早上.

很长一段时间我一直在努力解决同样的问题.我的解决方案实际上是安装功能IIS 6 Metabase Compatiblity.之后没有问题.一些帮助我的文章在下面

我在ASP.net中有一个Asynchronus IHttpHandler,我在ELMAH捕获中看到了这个异常错误.

Windows Server 2008 R2 Web Edition
IIS 7.5
ASP.NET
.NET 4.0运行时
在站点上运行HTTP.

谁能对这一个有所了解？谷歌列出了2008年左右的一些结果,关于.NET 2.0中关于在请求体的Read()函数期间断开HTTP的错误.

这是IIS7的基础非托管层(webengine.dll)报告的错误.在一些谷歌搜索后,最相关的线程似乎表明这是由于网卡驱动程序配置( TCP Offloading)的错误.
